Samsung Z4 lunched on 4/5/2017.it lunched with black shine coloer and its have a 4.5 curved display like samsung s8+ . It dont have extra fetchers then other phones.but its fetchrs is good to this price.its have 1gb ram and 8gb internal memory, 1.5 Quard-core prosser.
Its opperting systm is TIZEN OS v3.0.
Tizen os is a new opperating systm which is lunched in 2016.so its not good.
Its a 4g phone. Its win my heart. I will rat it 5.0stars.
By.By.By.By HAVE A NICE DAY.
